Correlative elaboration of key molecules including FCER1G, ZGMM, KIR2DL4, KIR3DH5, KLRC1, KLRB1, and FKBP5 among the 5 cell‐type clusters in evolutionary development trajectory of NKT for immune escalation against evasion of vital tumor cells and mutants was further illustrated by Violin plots (Figure S3g). The gene discussed is KIR2DL4; the disease is neoplasm.
